I upgraded today and... VMWare Fusion doesn't launch, because it's incompatible with MTL. 1. That is just bs, 2. VMWare wants $49.99 to upgrade. Second complaint- remember that Mac commercial with the dipshit in the blue shirt and the fat guy with a man who appeared to be a Secret Service Agent behind him? Yeah that's the one, where Apple mocked Windows for asking all the security questions. Guess who does that now? You guessed it, Mountain Lion. He's your new security guard and by default he won't let you install apps from outside the App Store or people who are verified by Apple. This is ridiculous. Last Mac I own, and I'm switching wholesale to Linux. Thanks Crapple.
